Odd-Z elements. The wavelength regions are centered at the five selected sodium lines (we note that only the two H-band lines were used to estimate the mean [Na/Fe] in Figure 6) for the star 2M06052796-0553384 (star 5), at the seven selected aluminum lines for the star 2M14275833-6147534 (star 25), and at the two selected potassium lines for the star 2M13403516-5040261 (star 19). Arrangement of figures and plot descriptions are similar to Figure A.1.
